This invention relates to improvements in corner reenforcements for containers.

Containers are subjected to strenuous handling by the user, and when the containers are constructed of fibreboard or similar material, they frequently become torn along the corner edges adjacent the ends of the upper flaps. In fibreooard containers, as ordinarily constructed, a tear of this type will soon become increased in length until the container is rendered unfit for further use.

It is one of the objects of this invention to provide an improved corner reenforcement for containers which will either entirely prevent tearing, or so limit the extent thereof as not to lessen the efficiency of the container for further use.

A further object of this invention is to provide an improved corner reenforcement for containers which is simple in construction, inexpensive, and well adapted for the purpose described.

With the'above and other objects in view, theinvention consists of the improved corner reenforcement for containers, and all its- .parts and combinations, as set forth in the claims, and all equivalents thereof.

In the accompanying' drawings in which the same reference numerals designate the same parts in allof the views:

Fig. 1 is a perspective view of a container with the improved corner reenforcement embodied therein;

Fig. 2 is an enlarged detail view of a portion of a container in knockdown formv showing the preferred form of reenforcing means;

Fig. 3 is an enlarged sectional view taken on line 3-3 of Fig. 2, parts being broken away;

Fig; 4 is a fragmentary view showing` the reenforcing means as it appears on the inside of the container;

Fig. 5 is a fragmentary view of a container showing a modified form of reenforcement;

Fig. 6 is a fragmentary horizontal sectional view showing said modification;

Fig. 7 is a fragmentary view showing an additional modification;

Fig. 8 is a fragmentarylview showing lstill another modification; l p

Figs. 9 and 10 are perspective views `of containers showing modifications; Y

Fig. 1l is a perspective View cfa container with the flaps at both ends open'showing an additional modification; and

Fig. -12 is a fragmentary plan view of'a container illustrating another modification.

Referring to the drawings, the numeral 10 designates the body portion of a *contayinen the said body portion being formed from@ blank which is folded upon lines of 'scoring 11 to form corners. Flaps 12, 'whichform4 a, closure for the container, are' foldable'with respect to the body". portion along lines of scoring 13.

In the preferred form of reenforcement.

rows of stitching 14 are inserted in the fibreboard transversely of the lines-of scoring 11j adjacent the upper edge ofthe container.

The said stitching may be in four relatively short rows adjacent each corner asshown in Fig. 1, or a continuous line of stitching encircling the entire container may be utilized, as illustrated in Fig. 9.

A further modification shown' in Fig. 10

utilizes a plurality of separated rows vlof stitching, some intermediate of the sides to prevent breaking open thereof'due to bulglng.

In the modification shownin Fig. 8,`the

stitching is inthe form of a U extending transversely of the linesl of scoringl 11, andv In Fi 7, still another modification is presente In this form of reenforcement, a strip of tape 14 is secured transverselyy of the corners by means of an adhesive.

distance along the corner lines of scoring 11,l

and the body portion wi1l.be held together by the reenforcing means. Thus the containers ma be utilized for a considerable length of time for various purposes without danger of their efficiency being impaired by rough and careless handling.

What we claim is:

l. In a container constructed of material capable of being torn and having a line of "fold therein, reenorcing stitching in said` material and extending transversely of the line of fold to limit tearing along said line of fold.

2. In a container constructed of materialV capable of being torn and having corner portions, reenforcing stitching in said material and extending transversely of the corner portions to limit tearing along said corner portions.

3. In a container constructed of material capable of being torn and having corner portions, reenforcing stitching in said material adjacent the upper edge of the con- I tainer extending transversely of the corner portions to limit tearing along said corner portions.

4. In a container constructed of material capable of being torn and having an opening therein for the reception of goods, reenforcing stitching in said material adjacent said opening for limiting tearing originating at said opening.

5. In a container constructed of material capable of being torn and having an opening therein for the reception of goods, reenforcing stitching in said material for limiting tearing thereof.

6. In a container constructed of material capable of being torn and having a corner portion and foldable flap portions, reenforcing means extending transversely of said corner portion and extending transversely of the line of fold of an adjacent flap portion.

7. In a container constructed of material I capable of being torn and having a corner portion and foldable flap portions, reenforcing stitching in said material extending transversely of said corner portion and extending transversely of the line of fold of an adjacent flap portlon.

8. In a container constructed of material capable of bein torn and having a corner portion and foldable flap portions, substantially U-shaped reenforcing means extending transversely of said corner portions and extending transversely of the lines of fold of the adj acentiiap portions.

9. In a container constructed of material capable of being torn and having a corner portion and foldable flap portions, substantially U-shaped reenforcingfstitching extending transversely of said corner portions and extending transversely ofthe lines of fold of the adjacent flap portions.

10. In a container formed of a blank of material capable of being torn, said blank having a flap at one end foldable adjacent a corner of the Acontainer for securing to the opposite end of the blank, reenforcing stitching extending transversely of said corner of the container to limit tearing therealong and extending lengthwise of said fiap to secure the latter to the opposite end of the blank.

In testimony whereof, We aiiix our signatures.
